Network security is a serious matter. A network allows you to share information and resources, but it also lets computer viruses, human intruders or even disgruntled employees do far more damage than they could on a single machine. Think about what would happen if every bit of data on your local area network (LAN) vanished, and you'll understand why security is so important. is a brief list of security measures to think about when you're installing a LAN: - Virtual data still requires physical security. This could mean keeping your server in a locked room, removing disk drives from workstations that don't need them and installing an alarm system in your office. All the security software in the world won't stop someone from breaking into your office and carting off .
- Beware of bugs. Most computer viruses are just a nuisance, but it only takes one malevolent virus to bring your network to its knees. Install reliable antivirus software, keep it updated and train your employees to use it. Install a firewall. If you connect your LAN directly to the Internet, configure a firewall to screen both incoming and outgoing traffic.Useful links:
